Among species of oleaginous plants grown in Romania, a high-ranking position is held by varieties of sun flower. During cultivation, harvesting, storing and processing the risk of mycotoxicological pollution is present. Another of the problems is that sun-flowers are utilized in the cold extraction of cooking oil on low- or average Output pressing devices were the ongoing process is not always under control. The aim of our research work has been the study of seed- and residue quality (cakes), residues resulting from processing with several privately owned units located in Transylvania. Material and Method There were drawn a number of 20 samples (10 of seed and 10 of oilcakes), and submitted to certain investigations: taste characteristics; gross chemical composition (performed by means of classical methods); freshness of the proteins - free ammonia; freshness of fats-contents in free fatty acids and, examinations for germs (NTG/g produce); also, for mycetes (load and identification of prevailing species). Data on the chemical composition were helpful in establishing the feeding values. The results obtained have led to the following conclusions: a number of 14 samples have displayed various alterations in quality macroscopically detectable (Iow purity and faulty taste); then, in chemistry also (high water content, i.e., above 12 p.c. with twelve samples). The high water content correlated with the mycotic load of well over 200 thousand colony-forming units (CFU)/gram. The prevailing mycetes were yeasts and species of Penicillium, Fusarium, Alternaria genera, of high mycotoxicogenic Potential. The feeding value in six samples of oilcake was below the limits provided by literature data. Finally suggestions for measures to be taken towards lowering the alimentary risks both in man and in animal are also made.
